PROCESS FOR THE rnonuo'rron OF A SOLUBLE Patented Oct. e, 1908.

To all whom tt'mag concern:

Be it known that I, FERDINAND FIu'TsoHE,

"a subject of the Emperor of Austria-Hungary, and resident of Rumburg, in the E1n pire of Austria-Hungary, have invented a certain new and useful Process for the Pro.-

'duction of a Soluble Gum, of which the fol lowing is an exact specification.

The present invention relates to 'gumsinsoluble in water such as algae or l chen, which. by means of an addition of a small quantity of p'erbora'te are transformed into a- .solubl-eform. The products referred to are well known in commerce as East Indian gum, Bassorine gum, insoluble gum" and so on. Further the products called traganthin gum, agar-agar, carrageen-moss, Icelandmoss and the like may also be treated withby first soaking them in cold water ant then boilin same under increase of pressure for 10-12. ours. I I

One of the above mentioned products, the

I I agar-agar has been made soluble by treating same with ozone. Such a proceeding however is rather expensive and as only afew textile establishments are equipped with ozonizing plants and as such factories taken collectively constitute the largest consumers of insoluble gums, the process forming the 1m y adapted for such works. t

The production of perborates is carried out on lines as fully described in my c0 ending application, Serial No. 410650, filed 1 anuary objIect of the present invention is particui 13, 1908. Though all such prepared perbo 1 rates contain borax, said addition does no harm,-if said perborate is employed for the purpose of finishing textile wares, on the contrary, it in a measure promotes the desired efi'ect. Thetuse of perborates reduces the time required for the boiling manipulation considerable and moreover it produces a far more soluble end product than any priorproceeding. The perborate employed may have the following formula:

NaBO, N gro, 1411p. The perborates'are employed in the follow} the like-is soaked in a solution of perborate, when it is afterwards heated under addition of water until the'whole solution attains the required thickness. As a rulethe' quantity of perborate employed amounts to'l per cent. of the weight of the.gun1-product selected. The resulting product is a soluble gum.

1, A soluble gum consisting of an insoluble product being soaked in a diluted perborat solution and afterwards heated.

2. Process for'the production of a soluble gum consisting in soaking an insoluble gum product, such as algae" or lichen, ina diluted perborato solution, heating the same under ing way: The natural gum product algae or gum product, such as algaeor lichen, said.

addition of watenuntil the required thickness of the solution is obtained, substantially as described. I I I In witness whereof I have hereunto set my hand in the presence of two wltnesses.
